The invention relates to a switched reluctance motor power circuit device containing an intelligent power model and an implementation method. The device comprises a 7 unit IPM, a power driving circuit, a circuit sampling circuit, an overvoltage and undervoltage detection circuit, a trouble detection circuit, a digital power supply part, and a switched reluctance motor. The invention can be used for assembling a high-performance switched reluctance motor servo system; and has the advantages of high efficiency, good energy saving effect, wide speed regulation range, no inrush starting current, large starting torque, flexible control, simple structure, firmness, good reliability, and low cost. The invention has wide application range, can replace the existing electric transmission speed regulation system (such as DC speed regulation system and variable frequency speed regulation system), and can be used in driving of transportation vehicles, table planning machine, heavy-load startup of various machines, frequent startup and forward and backward rotation, and long-term low-speed operation.
